Practical Scenario
With the increasing scarcity of fossil fuels, solar energy has become an important part of the energy used by human beings and is constantly being developed. are two ways to utilize solar energy: photothermal conversion and photoelectric conversion. Solar power generation is a new type of renewable energy. Solar cells are devices that directly light energy into electrical energy through the photoelectric effect or photochemical effect. When the sun shines on the solar panel, part of it is reflected by the surface, the rest is absorbed or transmitted by the solar panel. The absorbed light energy is converted into electrical energy in the form of generating electron-hole pairs
